| 摘要 |
The present invention proposes an ultrasonic flow meter, comprising a conduit for measurement in which a liquid flows therein, and a pair of measurement sections which are provided in said conduit for measurement and are spaced apart by a certain interval along its longitudinal direction, and which obtains the flow velocity of said flowing liquid from the difference in the propagation time periods of ultrasonic in the two opposite directions between these measurement sections, and thereby measures the flow rate thereof, wherein a pair of fixing portions are provided which respectively support said conduit for measurement at the exterior side and also at the interior side in the longitudinal direction of said measurement sections.
